Assertion : Molarity of a solution in liquid state changes with temper

1.	Assertion : Molarity of a solution in liquid state changes with temperature.Reason : The volume of a solution changes with change in temperature.
Answer» Assertion and reason both are correct statements and reason is correct EXPLANATION for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion and reason both are incorrect statements. Solution :Explanation : (i) Strength of a solution in terms of .Molarity (M). is represents the number of moles of the solute dissolved per litre of solution, i.e., Molarity `= ("No. of moles of solute component")/("Volume of solution in LITRES")` (ii) Since volume of a liquid varies with changes of temperature, the volume of solution WOULD also change while the number of moles of solute PRESENT in it will REMAIN the same (or unchanged). This therefore, would affect the molarity of the solution.
